Description

Technical Field

[0001] The present invention belongs to the technical field of precious metal storage equipment, and more specifically, relates to a safe. Background Art

[0002] A safe, also known as a safe deposit box, is a common device used by people in daily life to protect the safety of property, information, and personal belongings. It has a high popularity and practicality. Among the many safes, safes used for temporarily storing precious metals such as gold and platinum are more common.

[0003] Generally, safes used for temporarily storing precious metals often have their doors set on the top of the box body, with a delivery port opened on the door, and a shutter or the like to open or uncover the delivery port. Users or precious metal delivery devices such as gold exchange machines can directly deliver precious metals through the delivery port, without opening the door when delivering precious metals, which is convenient to operate. When the precious metals in the safe need to be taken out, the door can be opened. Therefore, a locking mechanism for controlling the opening or closing of the door needs to be set on the safe, and a locking mechanism for controlling the opening or closing of the shutter also needs to be set, that is, at least two sets of locking mechanisms need to be set in the safe to control the opening and closing of the door and the shutter respectively. The locking mechanism occupies a large space, which is not conducive to the miniaturization and lightweight production of the safe, and the production and maintenance costs of the safe are difficult to reduce. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a safe to solve the technical problem that safes in the prior art need to be provided with different locking mechanisms to respectively control the opening and closing of the box door and the opening and closing of the delivery port.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a safe, comprising:

[0006] The box body is open at the top and has a receiving cavity for receiving the precious metal formed therein;

[0007] A box door is hinged to the top of the box body and is used to cover the top opening of the box body. The box door is provided with a delivery port connected to the accommodating chamber. A shield capable of covering the delivery port is slidably connected to the box door. The shield can slide and move under the drive of an external driving shaft to open or cover the delivery port.

[0008] The locking mechanism includes a driving member installed on the box body, a locking member slidably installed on the box body and connected to the output shaft of the driving member, and a stopping member installed on the box door and linked to the locking member. The box door is provided with a locking member that is locked with the locking member, and the driving member can drive the locking member to reciprocate between a first preset position, a second preset position and a third preset position. When the locking member moves to the first preset position, the locking member is locked to the locking member and the stopping member holds the baffle against the delivery port. When the locking member moves to the second preset position, the locking member is locked to the locking member and the stopping member avoids the baffle. When the locking member moves to the third preset position, the locking member is disengaged from the locking member and the stopping member holds the baffle against the delivery port.

[0009] Further, the locking member is arranged in front of the shield along the sliding movement direction of the shield, the stopping member is rotatably connected between the shield and the locking member, one end of the stopping member is connected to the locking member, and the other end of the stopping member faces the shield, and a side of the shield facing the locking member is provided with an avoidance opening for the stopping member to fit through;

[0010] When the locking member is located at the second preset position, the length direction of the stop member is parallel to the sliding direction of the baffle, and the other end of the stop member is opposite to the avoidance opening; when the locking member is located at the first preset position or the third preset position, the length direction of the stop member intersects with the sliding direction of the baffle, and the other end of the stop member abuts against the side of the baffle.

[0011] Furthermore, the end of the stop member away from the locking member is bent upward to form a stop ear, and the end of the baffle plate close to the stop member is bent downward to form a stop ear. When the locking member is located at the first preset position or the third preset position, the stop ear is in contact with the stop ear.

[0012] Further, the locking member includes a first crossbar installed on the side of the box door and hooks vertically arranged at both ends of the first crossbar and extending downward to the side of the box body, the locking member includes a second crossbar slidably connected to the inner side wall of the box body and two hanging rings rotatably connected to the inner side wall of the box body, the two hanging rings are correspondingly arranged on the sides of the two hooks and linked with the second crossbar, and the stopper is connected to the second crossbar;

[0013] When the locking member is located at the first preset position or the second preset position, the two hanging rings are correspondingly hooked on the two hooks, and when the locking member is located at the third preset position, the two hanging rings are separated from the two hooks.

[0014] Furthermore, a connecting long hole is provided on the second cross bar, and the length direction of the connecting long hole is parallel to the sliding movement direction of the second cross bar. The length of the connecting long hole is greater than or equal to the interval length between the first preset position and the third preset position. A connecting pin is protruding from the inner wall of the box body at a position opposite to the connecting long hole, and the connecting pin is inserted into the connecting long hole.

[0015] Furthermore, a connecting arm is vertically arranged at the middle position of the second cross bar, the stop member is connected to the connecting arm, and the locking mechanism also includes a first microswitch and a second microswitch which are respectively arranged on both sides of the connecting arm and are communicatively connected to the driving member. When the locking member is located at the first preset position, the connecting arm moves to trigger the first microswitch, when the locking member is located at the second preset position, the connecting arm is located in the middle of the first microswitch and the second microswitch, and when the locking member is located at the third preset position, the connecting arm moves to trigger the second microswitch.

[0016] Furthermore, the driving member is a driving motor whose output shaft is arranged parallel to the second cross bar, and the output shaft of the driving motor is connected to the second cross bar through a transmission plate. The locking mechanism also includes a third micro switch arranged beside the output shaft of the driving motor and communicatively connected to the driving member. When the locking member is located at the second preset position or the third preset position, the transmission plate moves away from the end of the second cross bar to trigger the third micro switch.

[0017] Furthermore, the box door includes a detachably connected cover plate and door panel, the cover plate is adapted to cover the top opening of the box body, the door panels are stacked on the cover plate at intervals and form an installation cavity between the cover plate, the delivery port is opened on the cover plate, and a positioning port adapted to the delivery port is opened at a position of the door panel facing the delivery port, the shield plate is installed in the installation cavity and is slidably connected to the cover plate or the door panel, and a connecting portion for connection to an external drive shaft is provided on the shield plate, and the connecting portion exposes the positioning port.

[0018] Furthermore, the connecting portion is a protrusion protruding from the top edge of the baffle, and the periphery of the positioning port is symmetrically provided with a first notch and a second notch along the sliding movement direction of the baffle. When the baffle covers the delivery port, the protrusion is located in the first notch, and when the baffle moves to open the delivery port, the protrusion is located in the second notch.

[0019] Furthermore, the box door also includes a sensing component installed in the installation cavity, and the sensing component includes a fourth microswitch and a fifth microswitch which are communicatively connected to the external drive shaft and are used to detect the position of the shutter. The fourth microswitch and the fifth microswitch are arranged at intervals along the sliding movement direction of the shutter. When the shutter covers the delivery port, one end of the shutter moves to trigger the fourth microswitch, and when the shutter moves to open the delivery port, the other opposite end of the shutter moves to trigger the fifth microswitch.

[0020] The above one or more technical solutions in the safe provided by the present invention have at least one of the following technical effects: a locking mechanism is provided to control the opening and closing of the box door and the shutter at the same time. Specifically, when the box door is closed and the delivery port is closed, the locking member is locked to the locking member, and the stopping member stops the shutter on the delivery port. At this time, the locking member is located in the first preset position; when it is necessary to open the delivery port to deliver precious metals when the box door is closed, the driving locking member is driven by the driving member to move from the first preset position to the second preset position. At this time, the locking member is still locked to the locking member, and the stopping member moves under the driving of the locking member. The shutter is moved to avoid the opening of the shutter. In this way, the shutter can be driven by the external drive shaft to slide to open the delivery port, and the external precious metal can be dropped into the storage chamber of the box through the delivery port. After the delivery is completed, the driving member drives the locking member to return to the first preset position, and the shutter covers the delivery port; when it is necessary to open the box door to take out the precious metal from the storage chamber, the driving member drives the locking member to move to the third preset position. At this time, the locking member disengages from the locking member, and the box door can be opened. During the opening process of the box door, the shutter is always stopped by the stopping member on the delivery port, and the shutter will not slide and wear when the box door is opened and closed. In this way, a set of locking mechanisms can be set to realize the opening and closing control of the box door and the shutter, the space occupied by the locking mechanism is reduced, and the overall weight and volume of the safe are reduced, which can meet the development needs of lightweight and miniaturized safes, and only one locking mechanism is set, which makes the inspection and maintenance of the locking mechanism more convenient, and the inspection and maintenance costs are reduced.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0051] like Figures 1 to 7 As shown, an embodiment of the present invention provides a safe, which is applicable to but not limited to temporarily storing precious metals such as gold and diamonds. In particular, the safe can also be placed in precious metal storage devices such as gold exchange machines and safes to transfer precious metals in the gold exchange machines and safes. Specifically, Figures 1 to 4As shown, the safe comprises a box body 10, a box door 20 and a locking mechanism 30, wherein the box body 10 is open at the top and has a receiving cavity 11 for receiving precious metals formed therein. When the precious metals are transferred, the precious metals are received in the receiving cavity 11; one end of the box door 20 is hinged to the side of the box body 10 through a hinge 13, and the box door 20 is used to cover the top opening of the box body 10. A delivery port 21 connected to the receiving cavity 11 is provided on the box door 20. When the precious metals are transferred, the precious metals are delivered into the receiving cavity 11 through the delivery port 21. A shield plate 22 capable of adapting to cover the delivery port 21 is slidably connected to the box door 20, and the shield plate 22 can slide and move under the drive of an external drive shaft (not shown) to open or cover the delivery port 21, as shown in FIG. Figure 3 and Figure 4 Specifically, the external drive shaft can be, but is not limited to, a drive shaft that is disposed in a cash exchange machine or a safe and can reciprocate along the sliding direction of the shield 22 .

[0052] Furthermore, if Figure 2 , Figure 3 combine Figure 4 As shown, the locking mechanism 30 includes a driving member 31 installed on the box body 10, a locking member 32 slidably installed on the box body 10 and connected to the output shaft 311 of the driving member 31, and a stopping member 33 installed on the box door 20 and linked to the locking member 32. The box door 20 is provided with a locking member 23 that locks with the locking member 32. The driving member 31 can drive the locking member 32 to reciprocate between the first preset position, the second preset position and the third preset position. When the locking member 32 moves to the first preset position, the locking member 32 is locked to the locking member 23 and the stop member 33 holds the shield 22 against the loading port 21. At this time, the box door 20 is locked to the box body 10, the shield 22 covers the loading port 21, and the precious metals in the accommodating cavity 11 are sealed in the box body 10. When the locking member 32 moves to the second preset position, the locking member 32 is locked to the locking member 23 and the stop member 33 avoids the shield 22. At this time, the box door 20 is locked to the box body 10, the box door 20 covers the top opening of the box body 10, and the stop member 33 avoids The shutter 22 is opened and can be moved to open the delivery port 21 under the drive of the external driving shaft, ensuring that the external precious metals can be dropped into the accommodating chamber 11 through the delivery port 21 when the box door 20 is blocked; when the locking member 32 moves to the third preset position, the locking member 32 disengages from the locking member 23 and the abutting member 33 holds the shutter 22 on the delivery port 21. At this time, the box door 20 is unlocked and can be flipped open with its hinge axis as the axis, so that the precious metals in the accommodating chamber 11 can be taken out from the top opening of the box body 10.

[0053] In this embodiment, if Figure 3 , Figure 4 and 5As shown in the figure, the driving member 31 drives the locking member 32 to reciprocate between the first preset position, the second preset position and the third preset position, which means that the driving member 31 drives the locking member to move back and forth along the directions shown by F1 and F2 in the figure. Figure 1 As shown, when the locking member 32 is in the first preset position, the locking member 32 is locked to the locking member 23 and the abutting member 33 holds the shield 22 against the delivery port 21, the box door 20 is locked to the box body 10, and the shield 22 covers the delivery port 21. At this time, the locking member 32 is located at the limit position in the F2 direction; when it is necessary to deliver heavy metals through the delivery port 21 without opening the box door 20, the driving member 31 drives the locking member 32 to move in the F1 direction. When the locking member 32 moves to drive the abutting member 33 to move in conjunction with the locking member 32, the locking member 32 is locked to the locking member 23 and the shield 22 is locked to the delivery port 21. When the locking member 33 moves to avoid the shutter 22, the locking member 32 is located in the middle position between the F1 and F3 directions, that is, the locking member 32 is in the second preset position. At this time, the shutter 22 can slide to open the delivery port 21; when the box door 20 needs to be opened, the driving member 31 drives the locking member 32 to continue to move in the middle F1 direction. When the locking member 32 moves to disengage from the locking member 23, the locking member 32 is located in the third preset position. At this time, the locking member 32 is located at the limit position in the F1 direction, and the box door 20 can be opened.

[0054] The safe of the embodiment of the present invention is provided with a locking mechanism 30 to control the opening and closing of the door 20 and the shutter 22 at the same time. Specifically, when the door 20 is closed and the loading port 21 is closed, Figure 3 As shown, the locking member 32 is locked to the locking member 23, and the stopping member 33 stops the shutter 22 on the delivery port 21. At this time, the locking member 32 is located in the first preset position; when it is necessary to open the delivery port 21 to deliver precious metals when the box door 20 is closed, the driving locking member 32 is driven by the driving member 31 to move from the first preset position to the second preset position. At this time, the locking member 32 is still locked to the locking member 23, and the stopping member 33 is driven by the locking member 32 to move to avoid the shutter 22. In this way, the shutter 22 can be driven by the external driving shaft to slide to open the delivery port 21. Figure 4As shown, the external precious metals can be put into the accommodating chamber 11 of the box body 10 through the delivery port 21. After the delivery is completed, the driving member 31 drives the locking member 32 to return to the first preset position, and the shutter 22 covers the delivery port 21; when it is necessary to open the box door 20 to take out the precious metals from the accommodating chamber 11, the driving member 31 drives the locking member 32 to move to the third preset position. At this time, the locking member 32 is disengaged from the locking member 23, and the box door 20 can be opened. During the opening process of the box door 20, the shutter 22 is always stopped on the delivery port 21 by the stopping member 33, and the shutter 22 will not slide and wear when the box door 20 is opened and closed. In this way, a set of locking mechanisms 30 can be set to realize the opening and closing control of the box door 20 and the baffle 22. The space occupied by the locking mechanism 30 is reduced, and the overall weight and volume of the safe are reduced, which can meet the development needs of lightweight and miniaturized safes. Only one locking mechanism 30 is set, and the inspection and maintenance of the locking mechanism 30 is more convenient, and the inspection and maintenance costs are reduced.

[0055] In another embodiment of the present invention, Figure 2 As shown, the box body 10 includes an outer shell 14 with an open top and an inner shell 15 embedded in the outer shell 14 and with an open top. The accommodating cavity 11 is formed in the inner shell 15. An installation gap 141 is reserved between the inner shell 15 and the side wall of the outer shell 14. The components of the locking mechanism 30 installed on the side of the box body 10 are all accommodated in the installation gap 141 and isolated from the accommodating cavity 11. The precious metal in the accommodating cavity 11 does not contact the locking mechanism 30, and the use of the locking mechanism 30 is not affected by the precious metal in the accommodating cavity 11.

[0056] In another embodiment of the present invention, Figure 3 , Figure 4 and Figure 5 As shown, the locking member 32 is arranged in front of the baffle 22 along the sliding direction of the baffle 22, that is, the locking member 32 is slidably installed on the side of the box door 20 and is located in front of the baffle 22, and the stopping member 33 is rotatably connected between the baffle 22 and the locking member 32 through the rotating shaft 332. One end of the stopping member 33 is connected to the locking member 32, and the other end of the stopping member 33 is opposite to the baffle 22, that is, the free end of the stopping member 33 is located in front of the baffle 22 when the baffle 22 slides to open the delivery port 21, and the side of the baffle 22 opposite to the locking member 32 is provided with an avoidance opening 221 for the stopping member 33 to fit through.

[0057] Specifically, in this embodiment, Figure 3 and Figure 4As shown in the figure, the stopper 33 is a straight rod. When the shield 22 slides along a straight line, the stopper 33 can pass through the avoidance opening 221. When the locking member 32 moves between the first preset position, the second preset position and the third preset position, its moving direction is perpendicular to the sliding movement direction of the shield 22, that is, the direction shown by F1 and F2 in the figure is perpendicular to the sliding movement direction of the shield 22. In this way, when the locking member 32 is located at the second preset position, the length direction of the stopper 33 is parallel to the sliding movement direction of the shield 22, and the other end of the stopper 33 is directly opposite to the avoidance opening 221, as shown in FIG. Figure 4 As shown, in this way, when the shield 22 slides forward to open the delivery port 21, the stopper 33 can pass through the avoidance port 221 to the bottom of the shield 22 to avoid the shield 22; when the locking member 32 is located at the first preset position or the third preset position, the length direction of the stopper 33 intersects with the sliding movement direction of the shield 22, as shown in FIG. Figure 3 As shown, the other end of the stop member 33 abuts against the side of the baffle 22 to stop the baffle 22 from sliding forward. Specifically, when the locking member 32 is located at the first preset position, the end of the stop member 33 away from the locking member is roughly toward the F1 direction, that is, the end of the stop member 33 away from the locking member is abutted against the side of the baffle 22 on the left side of the avoidance opening 221. When the locking member 32 is located at the third preset position, the end of the stop member 33 away from the locking member 32 is roughly toward the F2 direction, that is, the end of the stop member 33 away from the locking member 32 is abutted against the side of the baffle 22 on the right side of the avoidance opening 221. In this way, a stop member 33 is provided between the locking member 32 and the baffle 22 and is rotatably connected to the box door 20. The locking member 32 reciprocates between the first preset position, the second preset position and the third preset position along the F1 or F2 direction to drive the stop member 33 to rotate, so that the stop member 33 moves away from the end of the locking member 32 to face or avoid the avoidance opening 221, thereby realizing the opening and closing control of the baffle 22. The stop member 33 has a simple structure, a simple linkage relationship with the locking member 32, and is flexible and convenient to use.

[0058] Furthermore, in this embodiment, if Figure 3 and Figure 6 As shown, the end of the stopper 33 away from the locking member 32 is bent upward to form a stopper ear 331, and the end of the shield 22 close to the stopper 33 is bent downward to form a stopper ear 222. When the locking member 32 is located at the first preset position or the third preset position, the stopper ear 331 contacts the stopper ear 222 to stop the shield 22 from sliding. Furthermore, the setting height of the stopper 33 is lower than the bottom height of the shield 22, and the avoidance opening 221 is a notch set at the middle position of the stopper ear 222. In this way, when the locking member 32 moves to the second preset position, that is, the stopper 33 rotates to be parallel to the sliding movement direction of the shield 22, the stopper 33 can penetrate from the avoidance opening and move to the bottom of the shield 22, thereby completely avoiding the shield 22 and ensuring that the shield 22 can slide freely.

[0059] In another embodiment of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the locking member 23 includes a first cross bar 231 installed on the side of the box door 20 and hooks 232 vertically arranged at both ends of the first cross bar 231 and extending downward to the side of the box body 10, the two hooks 232 are respectively located on the left and right sides of the stop member 33, the locking member 32 includes a second cross bar 321 slidably connected to the inner wall of the box body 10 and two hanging rings 322 rotatably connected to the inner wall of the box body 10, the two hanging rings 322 are correspondingly arranged on the sides of the two hooks 232 and linked with the second cross bar 321, the stop member 33 is connected to the second cross bar 321, when the locking member 32 is located at the first preset position or the second preset position, the two hanging rings 322 are correspondingly hooked on the two hooks 232, when the locking member 32 is located at the third preset position, the two hanging rings 322 are correspondingly separated from the two hooks 232.

[0060] Specifically, in this embodiment, Figure 3 , Figure 4 and Figure 6As shown, two pins are provided at the positions of the inner wall of the box body 10 near the two hooks 232, and the two hanging rings 322 are rotatably connected to the inner wall of the box body 10 through the corresponding pins, and the first paddle 3213 and the second paddle 3214 are arranged at intervals at the two ends of the second cross bar 321. The hanging ring 322 located on the left side of the stop member 33, its end away from the hook 232 is clamped between the first paddle 3213 and the second paddle 3214 on the left side of the second cross bar 321, and the hanging ring 322 located on the right side of the stop member 33, its end away from the hook 232 is clamped between the first paddle 3213 and the second paddle 3214 on the right side of the second cross bar 321. The two hanging rings 322 can rotate under the push of their corresponding first paddle 3213 or second paddle 3214. Specifically, when the box door 20 is closed and the delivery port 21 is closed, that is, the locking member 32 is in the first preset position, the end of the hanging ring 322 is against the second paddle 3214, and the hanging ring 322 is thrust by the driving member 321 and tends to rotate counterclockwise, and the hanging ring 322 is hooked on the hook 232; when the delivery port 21 needs to be opened, the driving member 31 drives the locking member 32 to translate along the F1 direction, and the hanging ring 322 moves to be between the first paddle 3213 and the second paddle 3214. At this time, the hanging ring 322 is still hooked on the hook, the box door 20 is locked to the box body 10, and the stopping member 33 is driven by the second cross bar 321 to swing clockwise to the stop ear 331 to avoid When the box door 20 needs to be opened, the driving member 31 drives the locking member 32 to translate along the F1 direction, and the hanging ring 322 moves to abut against the second paddle 3214. The second paddle 3214 pushes the hanging ring 322 to rotate clockwise to make the hanging ring 322 disengage from the hook 232. At this time, the locking member 32 disengages from the locking member 23, and the box door 20 can be flipped open. At the same time, the stopping member 33 is driven by the second cross bar 321 to swing clockwise until the stop ear 331 passes over the avoidance opening 221, and the stop ear 331 abuts against the stop ear 222 of the baffle 22 from the right side of the avoidance opening 221 to ensure that the delivery opening 21 is closed when the box door 20 is opened.

[0061] In particular, in this embodiment, the end of the hanging ring 322 clamped between the first paddle 3213 and the second paddle 3214 is elastically connected to the first paddle 3213 and / or the second paddle 3214 through an elastic member such as a torsion spring to ensure that the hanging ring 322 can maintain an upright state and establish a positive and reliable hooking connection relationship with the hook 232.

[0062] Furthermore, in this embodiment, if Figure 5 and Figure 6As shown, a connecting long hole 3211 is provided on the second cross bar 321, and the length direction of the connecting long hole 3211 is parallel to the sliding direction of the second cross bar 321. The length of the connecting long hole 3211 is greater than or equal to the interval length between the first preset position and the third preset position. A connecting pin 12 is protruded at the position of the inner side wall of the box body 10 opposite to the connecting long hole 3211. The connecting pin 12 is inserted into the connecting long hole 3211. The driving member 31 drives the locking member 32 to slide under the guiding cooperation of the connecting pin 12 and the connecting long hole 3211. Specifically, when the locking member 32 is located at the second preset position, the connecting pin 12 is located at the middle position of the connecting long hole 3211; when the locking member 32 moves from the second preset position to the first preset position along the F1 direction, the locking member 32 drives the locking member 23 to slide and move until the connecting pin 12 is located at one end of the connecting long hole 3211; when the locking member 32 moves from the second preset position to the third preset position along the F2 direction, the locking member 32 drives the locking member 23 to slide and move until the connecting pin 12 is located at the other end of the connecting long hole 3211. Preferably, in this embodiment, the length of the connecting long hole 3211 is equal to the interval length between the first preset position and the third preset position, so that the moving stroke of the locking member 32 is limited, and the driving member 31 will not be closed in time and excessive movement will not occur, and the position switching of the locking member 32 is more accurate and the operation is more convenient.

[0063] In another embodiment of the present invention, Figure 5 and Figure 6 As shown, a connecting arm 3212 is vertically arranged at the middle position of the second cross bar 321, and the stopper 33 is connected to the connecting arm 3212. The locking mechanism 30 also includes a first micro switch 34 and a second micro switch 35 which are arranged on both sides of the connecting arm 3212 and are communicatively connected to the driving member 31. When the locking member 32 is located at the first preset position, the connecting arm 3212 moves to trigger the first micro switch 34. When the locking member 32 is located at the second preset position, the connecting arm 3212 is located in the middle of the first micro switch 34 and the second micro switch 35. When the locking member 32 is located at the third preset position, the connecting arm 3212 moves to trigger the second micro switch 35. In this way, by setting the first microswitch 34 and the second microswitch 35, the position status information of the lock component 32 can be obtained. When the first microswitch 34 is triggered, the lock component 32 is located at the first preset position, and the box door 20 and the delivery port 21 are both in the closed state; when the first microswitch 34 and the second microswitch 35 are not triggered, the lock component 32 is located at the second preset position, the box door 20 is closed, and the delivery port 21 can be opened; when the second microswitch 35 is triggered, the lock component 32 is located at the third preset position, the delivery port 21 is closed, and the box door 20 can be opened.

[0064] Furthermore, if Figure 5 and Figure 6As shown, the driving member 31 is a driving motor with an output shaft 311 parallel to the second cross bar 321. The output shaft 311 of the driving motor is connected to the second cross bar 321 through a transmission plate 312. The locking mechanism 30 also includes a third micro switch 36 arranged beside the output shaft 311 of the driving motor and communicatively connected to the driving member 31. When the locking member 32 is located at the second preset position, the transmission plate 312 moves away from the end of the second cross bar 321 to trigger the third micro switch 36. In this way, when the driving member 31 drives the locking member 32 to move to the second preset position, the third micro switch 36 is triggered, and the driving member 31 promptly controls the closing of the driving member 31 to prevent the driving member 31 from continuing to drive the locking member 32 to move away from the second preset position, thereby further improving the accuracy of the position switching of the locking member 32.

[0065] Specifically, in this embodiment, Figure 5 and Figure 6 As shown, the safe also includes a controller (not shown) electrically connected to the driving member 31. The first microswitch 34, the second microswitch 35 and the third microswitch 36 are all communicated with the driving member 31 through the controller. When the locking member 32 moves to a specific position, the corresponding microswitch can immediately feedback the position information of the locking member 32 to the controller, and the controller then promptly controls the closing of the driving member 31. In this way, the start and stop control of the driving member 31 is more automated and intelligent, and more operable.

[0066] Preferably, in this embodiment, the first micro switch 34 , the second micro switch 35 and the third micro switch 36 may all be mechanical micro switches or inductive micro switches.

[0067] In another embodiment of the present invention, Figure 5 As shown, a Hall sensor 16 electrically connected to the controller is also provided at a position of the box body 10 near the box door 20 , and the Hall sensor 16 is used to sense the opening and closing status of the box door 20 .

[0068] In another embodiment of the present invention, Figure 4 and Figure 5 As shown, the locking mechanism 30 also includes a mechanical lock 37 arranged at one end of the locking member 32. The mechanical lock 37 can be a common password lock or a lock with a key. A spare opening (not shown) is opened at the position of the lock tongue 371 of the mechanical lock 37 in the box door 20. Under normal circumstances, the spare opening is covered by a sealing plate 372. In an emergency, such as when the driving member 31 cannot be started, the sealing plate 372 can be pushed open by the lock tongue 371 of the mechanical lock 37. At this time, a screwdriver or a wrench can be inserted into the spare opening. The screwdriver or the wrench pulls the locking member 23 to disengage its hook 232 from the hanging ring 322 of the locking member 32, thereby opening the box door 20.

[0069] Specifically, in this embodiment, Figure 4 , Figure 5 and Figure 6 As shown, the box door 20 is provided with a connecting column 28, and the first cross bar 231 is provided with a connecting short hole 2311 perpendicular to the sliding movement direction of the shield plate 22. The length of the connecting short hole 2311 is equal to the interval length between the second preset position and the third preset position. The first cross bar 231 is slidably installed on the side of the box door 20 along the sliding movement direction perpendicular to the shield plate 22 through the connecting column 28. When the box door 20 is locked to the box body, the cover plate 372 stops the first cross bar 231 and makes the connecting column 28 located at one end of the connecting short hole 2311 away from the cover plate. When the cover plate 372 is pushed open by the lock tongue 371, the locking member 23 can slide along the F1 direction under the action of an external tool such as a screwdriver or a wrench until the connecting column 28 is located at the other end of the connecting short hole 2311. At this time, the hook 232 of the locking member 23 is separated from the hanging ring 322 of the lock member 32, and the box door 20 can be opened. In this way, by setting the locking member 23 to move relative to the door 20 , it is ensured that the door 20 can be opened when the locking mechanism 30 fails.

[0070] In another embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the box door 20 includes a cover plate 24 and a door panel 25 that are detachably connected. Specifically, the cover plate 24 is locked to the bottom of the door panel 25 by fasteners such as screws, and the cover plate 24 is adapted to cover the top opening of the box body 10. The cover plate 24 is adapted to cover the top opening of the box body 10, and the door panels 25 are stacked on the cover plates 24 at intervals and form an installation cavity 241 with the cover plates 24. The delivery port 21 is opened on the cover plate 24, and a positioning port 251 adapted to the delivery port 21 is opened at a position of the door panel 25 facing the delivery port 21. The shield 22 is installed in the installation cavity 241 and is slidably connected to the cover plate 24 or the door panel 25. A connecting portion 223 for connecting an external drive shaft is provided on the shield 22, and the connecting portion 223 exposes the positioning port 251. When it is necessary to transfer precious metals, the safe of this embodiment is moved to a position where the positioning port 251 faces the precious metal output port on a precious metal delivery device such as a gold exchange machine or a safe, and then the driving shaft on the precious metal delivery device is moved to connect with the connecting portion 223, and the driving shaft drives the shutter 22 to move to open the delivery port 21. At this time, the precious metals in the precious metal delivery device can enter the accommodating cavity 11 through the delivery port 21. In this way, by setting the door panel 25 connected to the cover plate 24 and reserving the installation cavity 241, the shutter 22 is accommodated in the installation cavity 241, and the overall appearance is more beautiful. In addition, a positioning port 251 is opened on the door panel 25, and the positioning port 251 moves to face the output port of the precious metal delivery device, which means that the delivery port 21 is also synchronously moved to face the output port, and the movement reference is more obvious, so that the delivery port 21 and the output port can be effectively prevented from being skewed.

[0071] Furthermore, in this embodiment, the shield plate 22 can slide under the drive of the external drive shaft to open or cover the loading port 21. When the precious metal is not transferred, Figure 3 As shown, the shield 22 covers the delivery port 21 to prevent the precious metals contained in the accommodating chamber 11 from pouring out. When the precious metals are delivered, the delivery port 21 is placed just below the precious metal output port of an external delivery device such as a gold exchange machine and a precious metal safe. The external driving shaft on the external delivery device is connected to the connecting portion 223 on the shield 22. The shield 22 slides and moves under the drive of the external driving shaft to open the delivery port 21. After the delivery port 21 is opened, the precious metals in the external delivery device can be delivered into the accommodating chamber 11 of the box body 10 through the delivery port 21. Figure 4 As shown. In this way, when transferring and depositing precious metals, it is only necessary to control the external driving shaft on the external delivery device to be connected to the connecting portion 223 on the shutter 22, and the delivery port 21 can be opened synchronously by controlling the movement of the external driving shaft. In this way, the safe of this embodiment can work in coordination with external delivery devices such as gold exchange machines and precious metal safes. When depositing precious metals, there is no need to manually open and close the shutter 22, and the delivery operation is simpler, thereby effectively improving the transfer and delivery efficiency of precious metals.

[0072] In another embodiment of the present invention, Figure 3 , Figure 4 and Figure 7 As shown, two slide rails 224 are convexly provided at the positions of the opposite sides of the delivery port 21 at the top of the cover plate 24 or the bottom of the door plate 25, and the length direction of the two slide rails 224 is parallel to the sliding movement direction of the shield plate 22, and the opposite sides of the shield plate 22 are correspondingly clamped in the slide grooves of the two slide rails 224, that is, the two sides of the delivery port 21 are symmetrically provided with two slide rails 224, and the shield plate 22 is limitedly clamped between the two slide rails 224, and the slide rails 224 guide the movement of the shield plate 22, thereby guiding the shield plate 22 to accurately move to open or cover the delivery port 21, and the sliding movement of the shield plate 22 is more accurate. Specifically, in this embodiment, the two slide rails 224 are both arranged at the top of the cover plate 24 or at the bottom of the door plate 25, that is, the shield plate 22 can be slidably connected to the cover plate 24 or the door plate 25.

[0073] In another embodiment of the present invention, Figure 3 , Figure 4 and Figure 7As shown, since the driving shaft on precious metal delivery devices such as gold exchange machines and safes is often a rod-shaped driving shaft, such as a latch, in this embodiment, the connecting portion 223 is preferably a protrusion protruding from the top edge of the baffle 22, and a slot for the driving shaft to be adapted and inserted is provided on the protrusion. When the safe of this embodiment moves to the point where the positioning port 251 is opposite to the output port of the precious metal delivery device, the end of the driving shaft on the precious metal delivery device can be inserted into the slot on the protrusion. The periphery of the positioning port 251 is symmetrically provided with a first notch 2511 and a second notch 2512 along the sliding direction of the baffle 22. When the baffle 22 covers the delivery port 21, the protrusion is located in the first notch 2511. When the external driving member 31 drives the baffle 22 to move to open the delivery port 21, the protrusion moves to be located in the second notch 2512. In this way, the distance between the first notch 2511 and the second notch 2512 is equal to the inner diameter of the delivery port 21. When the protrusion moves from the first notch 2511 to the second notch 2512, the delivery port 21 can be fully opened. The moving stroke of the shutter 22 is fixed, and the reliability of moving to open or close the delivery port 21 is higher.

[0074] Furthermore, if Figure 3 and Figure 4 As shown, the box door 20 also includes a sensing component installed in the installation cavity 241, and the sensing component includes a fourth microswitch 26 and a fifth microswitch 27 which are communicatively connected to the external drive shaft and are used to detect the position of the baffle 22. The fourth microswitch 26 and the fifth microswitch 27 are arranged at intervals along the sliding movement direction of the baffle 22. Specifically, the fourth microswitch 26 is arranged at the rear end of the baffle 22, and the fifth microswitch 27 is arranged at the front end of the baffle 22. When the baffle 22 covers the delivery port 21, one end of the baffle 22 moves to trigger the fourth microswitch 26. When the baffle 22 moves to open the delivery port 21, the other end of the baffle 22 moves to trigger the fifth microswitch 27. In this way, when the fourth microswitch 26 is triggered, it means that the shutter 22 has moved to completely cover the delivery port 21. Conversely, when the fifth microswitch 27 is triggered, it means that the shutter 22 has moved to completely open the delivery port 21. The fourth microswitch 26 and the fifth microswitch 27 are combined with the first notch 2511 and the second notch 2512 to move and position the shutter 22, and the movement of the shutter 22 is more precise.

[0075] Furthermore, the fourth microswitch 26 and the fifth microswitch 27 can also be connected to the external drive shaft through the controller. In this way, when the fourth microswitch 26 and the fifth microswitch 27 are triggered, the external drive shaft can automatically and synchronously close the drive of the shutter 22. There is no need for the operator to manually control the opening and closing of the external drive shaft, and the opening and closing process of the delivery port 21 is more automated.

[0076] Preferably, in this embodiment, the fourth micro switch 26 and the fifth micro switch 27 can also be mechanical micro switches or inductive micro switches.

[0077] In another embodiment of the present invention, Figure 2 and Figure 5 As shown, the safe also includes a positioning module (not shown), a wireless communication module (not shown) and an alarm module (not shown) connected to the controller for communication. The positioning module and the wireless communication module are both installed in the box 10. A battery 50 is also provided in the box 10 to power the controller. The positioning module is used to sense the position of the safe and locate the safe. When the safe is lost, the position of the safe can be determined by the positioning module, so as to quickly find the safe. The wireless communication module is used to remotely send the position information of the safe detected by the positioning module to the controller, and send the position information of the safe to the operator as soon as possible. The alarm module is used to sound an alarm when the safe is abnormally activated. Specifically, in this embodiment, the positioning module can be a GPRS module, etc., the wireless communication module supports 2G mobile communication, 3G mobile communication, 4G mobile communication, 5G mobile communication and narrowband Internet of Things communication. The controller can be an STM32F401 microcontroller, an MCU controller, or a single-chip microcomputer, a PLC control device, a computer, etc. with relatively mature technology. The specific control of each of the above electric components can be performed according to the program set or edited according to the control and use requirements.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
